Matt Sparrow has joined Crawley following his release by Albion.
The midfielder had not made an appearance for the Seagulls this season and had his contract paid up yesterday.
Scunthorpe were interested in resigning the 31-year-old who spent 11 seasons with the Iron before moving to Sussex.
But Crawley made their move to tie up his signature following the departure of Hope Akpan to Reading on Tuesday.
Sparrow played nearly 400 games for Scunthorpe and twice helped them gain promotion to the Championship. He was also a regular in the Albion team which won League One two seasons ago before falling down the pecking order.
